BURNER,

Specification of Letters Patent.

Application filed May 20, 1915. Serial No. 23.264.

To all whom it may concern: I

Be it known that I, FRANn H. WARNER, of Toledo, Lucas county, Ohio, a citizen of I the United States of America, have invented new and useful Burners, of which the following is a specification.

This invention relates to combustion devices for liquid fuels.

This invention has utility when incorporated in burners for hydrocarbons, as crude petroleum and illuminating oils, for cooking, heating and boiler uses.

Referring to the drawings:

Figure 1 is a fragmentary view of an embodiment of the invention in a hot plate for cooking purposes and the general uses to which a stove may be put;

Fig. 2 is a fragmentary plan view of the burner proper;

Fig. 3 is a vertical section through the lower portion of the burner, with the air supply housing lifted for initial warming up of the burner from the wick;

Fig. 4 is a section on the line IVIV, Fig. 2;

Fig. 5 is a top plan view of one of the rings of the air supply housing;

Fig. 6 is a bottom plan view of the ring member of Fig. 5; and

Fig. 7 is a section on the line VIIVII, Fig. 5.

The liquid fuel may be supplied, say by gravity from the tank 1 through the duct 2, having its fiow controlled by the valve 3, for delivery by the passage 4 through the intake 5 in the bottom of the liquid fuel receiving chamber or annular well 6 in the burner base 7. In this instance, but one well is shown and that of circular form. Adjacent the top of the well 6 is a strip of asbestos wicking 8 on the ledge 9.

Mounted on the base 7 over the top of the well 6 is the air supply housing comprising the lower section or ring member 10 having the radially disposed partitions 11 therein downwardly extending into the well 6. These partitions 11 taper downwardly and provide heat conducting means submerging in the liquid fuel to assist vaporization, the depth of submergence adjusted by the valve 3 may vary the vaporization rate, and accordingly the burner adjustment may be changed.

The succeeding superposed members 12 of the air supply housing include a pair of concentric rings connected by partitions 13, radially extending and projecting on the lower side to space the member 12 from the housing member therebelow. The number of these members may be varied to meet special heating conditions or fuel variations. The showing herein has been found effective for kerosene oil fuel burning. The uppermost housing member 14 has an outwardly extending flange overlappincr the surrounding air deflector shell 15. C bncentrically disposed as to the outer deflector 15, is the inner reverse cone deflector shell 16 supported on the member 14. The members of the air supply housing may be assembled by the pins 17, 18, riveting them into the housing grouplng.

The well 6 of the base 7 is sustained by the bars 19 with which may coact notches 20 in the shell 15.

The article to be heated may be supported above the burner by the grid 21.

In operating the burner, the bail 22 may be used to lift the shell 15 and the interconnected mcmbers over the well 6. By opening the valve 3 sufficient fuel may be allowed to enter the well 6 to reach the wick 8. This fuel may be ignited, the shell 15 with interconnected members brought back to the base 7, but in placing thereon, it is disposed so that the notches 20 do not register with the bars 19, and accordingly the member 10 has its clearance adjusted as to the well 6 to permit sutlicient air supply for continued burning of fuel from the wick 8. When this burning has warmed the tapered partitions 11, a slight angular shifting of the shell 15 will bring the notches 20 and bars 19 into registry, and the clearance is reduced to extinguish the burning at the wick, while the vaporization effected by the warmed partitions l1, continues the combustion started at the wick 8, air supply for maintaining which burning enters in up draft travel through the base 7 as directed by the shells 15, 16, into the narrow ways between the housing members or rings 12, as spaced by the partitions 13. At the outlet region above the member 14 there is an annular series of burners of efficient intense heating action. The partitions give the burner uniformity of operation throughout its extent, with a stability against being ex- Patented Aug. 21, 1917.

tinguished by sudden drafts or air laterally ofthe burner. Furthermore, the added heating surface for. the air by the conducting partitions in addition to the ring heating of the air and the Warming by the shells, insures good combustion. The rising air currents through the base 7 keep the Well 6 cool, and the vaporization accordingly is not modified by the burner condition after starting, but is accurately controlled by the valve 3 regulating the liquid quantity exposed to the vaporization action of the fingers or tapered partitions 11. The deeper the submergence of these elements 11 in the 'oil, the greater heat radiation in theoil, and

accordingly, the greater the vaporization rate for supplying gas for the burner.

What is claimed and it is desired to secure by Letters Patent is:

1. A burner comprising a liquid fuel receiving chamber, and a partitioned air supply housing mounted onthe chamber, said partitions extending downwardly into the chamber to provide vaporization assisting heat conducting means.

2. A burner comprising a liquid fuel receiving chamber, and a series of members mounted thereon provided with projecting partitions to space the members for air supply therebetWeen, one of said members having heat conducting tapering means extending into the chamber.

3. A burner comprising an annular Well, and a succession of superposed vertically partitioned air supply housing forming rings thereon.

4. A liquid fuel burner comprising a Well, a Wick adjacent the Well, and a rotatably shiftable air supply housing having adjustable clearance as to the Wick, whereby the Wick may be used to Warm the housing, and the housing so warmed rotatably shifted to reduce the air supply adjacent the Wick by reducing the housing clearance at the Wick.

In testimony whereof I affix my signature.

FRANK H. WARNER.
